To all whom it may concem:

Be it known that I, FRANK E. BECKA, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Portable Lam s for Sewing Machines, Etc., of which the ollowing is a specification.

This invention relates to improvements in portable lamps and particularly to a type designed for attachment to a sewing machine in such a position as to direct light rays upon the article being stitched by the machine.

. It is an object of this invention-to provide a light which may be securely, yet removm'adiflerent positions and constructed so that aany of these positions may be maintained without possibility of it accidentally shifting due to vibration of the machine or other causes.

It is likewise an object to provide a portable lamp which may 'well be used in connection with other machines and devices aside from the sewing machine, association with which is the primary object. Other objects will be in art obvious and in part ointed out hereina r.

In or er that the invention and its mode of operation may be readily understood by persons skilled in the art, I have in the accompanying illustrative drawings, and in the following detailed descri tion based thereon set outpone possible em odiment of the same.

Figure "1 is a side elevation of a'sewing machlne head, this portable lamp being illustrated in operative osition;

Figure 2 is a detaile evation of the portable lamp; f

Figure 3 is a detail elevation taken at right angles to the illustration in Figure 2, and Y Fi ure 4 is a sectional view taken substantially on the line 4.4 of Figure 2.

Having more articular reference to the drawings throug out which similar characters of reference designate like parts this invention may be stated as comprising a socket 5 mounting the usual'switch finger piece 6, and having a rearwardly extending sleeve 7, through which the conductor 8 is led to the socket. Arranged upon the forward end 'of this socket and rigidly connected thereto 'is a tubular metal shield 9, which serves asv ameans for concentrating the light rays upon any particular point. This shield has one side portion cut away as shown in Figure '2 so the light rays may be projected therefrom. The forward end of this shield 9 is closed b means of a removable flanged cap mem er 10, the .rear end being closed in a similar manner except that the cap member 11 is welded or otherwise rigidly connected to shield and carries a lamp supporting portion 12.

The sleeve 7 heretofore referred to is rovtatable on a neck portion 13, so the lamp and its shield may be adjusted to project the light rays in the desired-direction. In order to retain this sleeve 7 at an adjusted point I provide a set screw 14 w ich binds against the neck 13, as shown in Figure 4. Diametrically opposite this set screw and integrally forme u on the sleeve 7 is a threaded stud 15 which mounts at'its other end avwing nut 16 whose purpose will be. apparent.

In order that this lam may be reliably attached to a sewing mac e head or other' support I provide a substantially 'U-shaped spr ng metal clip 17, formed of a single strip of metal bent upon itself as at 18, and being apertured at this oint to receive the aforementioned threade stud 15. From this folded oint the arms .19 are curved outwardly, t on inwardl and at the point 20 are arranged in para el'relationy-the end portions being to ded or bent inwardly upon themselves and provided with transversely alined o enin s designed to receive securin or locking bo ts %1. In a plication of this am to a sewing machine the bolt 21 is remove the arms 19 are slip ed over the sewing machine head and the It 21, is inserted into the o nings at the end of the arms and upontig tening the wing nut reliable connection is eifected. Should the. respective position of the opening in the shield 9 be incorrect, the set screw 14 may shield and its associated parts with res ect to the position of the clip. Further ad ust ment is permitted through loosening the be loosened so as .to permit shifting of the win .nut 16 carried by the sleeve, thls operation permitting horizontal swm the lamp shield and its associate with respect to the supporting clip.

Heretofore certain types 0 lamps have been designed for use about sewing ma- :5 f parts chines and the like but they have been asatisfactory because of the fact that they cannot be accurately adjusted to concentratethe light rays upon the desired point and the adjustment which is ossible cannot be maintained due to the a sence of} the means for reventing movement resulting from the vibration of the machine. These objections are entirely overcome through the use of the structure as herein brought out,

ll claim:

1. The combination with a sewing machine head of a substantially lit-shaped clip engageable with the head, said clip having a flat apertured arm between its ends, a socket, a neck carried by said socket, a sleeve rotatably mounted on. said neck, a stud carried by said sleeve and projecting through the apertures, means for locking the arm in an adjusted position with respect to the neck, an elongated tubular shield carried by the socket and having an opening in one'side, and an electric lamp arranged teaaeao y socket and having an opening in one side,

an electric lamp arranged in said shield and connected to the'socket, a neck axially alined with the socket and extending therefrom at the end opposite said shield, a sleeve loosely mounted upon the neck and carrying.

a threaded stud, a strip of sheet metal folded upon itself and forming an arm, said arm being apertured to fit over the stud, a air of outwardly curved arms extending rom a point adjacent the apertured arm and having a pair of transversely alined openings, a bolt receivable in said openings and a set screw carried by said sleeve whereby to permit adjustment of the shield and socket with respect to the clip.

In testimony whereof, I aflix my signature.
